What then do you mean that American cars/houses are unsustainable? I don't think big houses/cars is a good thing, but I think it probably is sustainable for quite a while (less climate concerns, in which case everything is unsustainable, depending on who you talk to) because we don't have the same density as Europe. I haven't thought much about this, but that's my hunch. I'd be really interested to hear counterarguments.
